Perch would be awesome!!! I can't even say how happy a mirror carp or linear would be to catch in this game. Hopefully You can get the help to get these fish in the game as new species are a blast to catch. I'd even love to see zander or walleye in the game but even if I could make pegs, to make one now would require fly fishing through holes in the ice, then again that could be a great skills challenge....hmmmm.
